In the message, the 35-year-old mother-of-two spoke from the heart about fearing for North West and Saint West's safety since they happen to be half-black themselves, saying:

"I want my children to grow up knowing that their lives matter. I do not ever want to have to teach my son to be scared of the police, or tell him that he has to watch his back because the people we are told to trust — the people who 'protect and serve' — may not be protecting and serving him because of the color of his skin.

The last thing we need is to fuel anger with more hate or violence, especially toward the many incredible police officers who risk their lives every single day to protect our families and communities. We must peacefully use the power of our voices and the strength of our numbers to demand changes in the judicial system so that brutality doesn't ever go unpunished."

Zayn previewed the duet by posting a black and white pic of himself with Swifty on his Instagram -- but hey, she is bestiez with his girlfriend Gigi Hadid, so it wouldn't be unusual that they hang out... But collab?!
